Future Me

I think I got this from one of my friends once, but it's pretty nifty. You can send yourself a letter, in the form of an e-mail... and choose a date, so that it'll send you your letter. So it's kind of like a time-capsule, but it's addressed just to you, and only with words instead of items, I guess?

I sent myself one back in March. But it's going to send it to me next March, I believe.

Haha thats pretty cool! I did that one time when my science teacher wanted me to write a letter to myself about my 'Earth day' resolutions and instead I asked myself some questions.
It was hilarious when I got it back at the end of the year, haha.
